PREFACE. 


Q \85- 

1346 


IN' response to the oft repeated and urgently pronounced requests 
of my large and generous constituency, I have much pleasure in 
presenting my first Catalogue to the kind perusal of themselves and 
the public. 

From the nature of the work it will, I am sure, without any 
further proof, be admitted that a large outlay of money, and an 
immense expenditure of time, have been demanded. Very many of 
the illustrations now appear for the first time in this country, and most 
of the representations have been drawn from the objects themselves. 
The work has, consequently, been delayed far longer than was 
intended, and now, although the utmost care has been taken, I 
should not like it to be received as perfect. Doubtless some inaccu¬ 
racies have crept in unawares, but these, I trust, will be found 
slight, and unimportant in character, and will, in consideration of 
the amount of work involved in the compilation, be gently criticized. 

The classification of the articles will be, as far as possible, 
alphabetical; and, for the further convenience of those using the 
Catalogue, an Index is added. In this the articles are, without any 
regard to their uses, arranged alphabetically, with a number an¬ 
nexed, which refers to the page upon which a description of the 
article may be found. 

It is well known that in apparatus which is imported, unimpor¬ 
tant variations in form are always liable to be found. In this respect, 
it will always be my endeavor to secure the style which shall contain 
the latest improvements, and be the most effective in operation. 
My bottles are all made on my own forms, and I can confidently 
give a guarantee that every article named in the following pages 
will be in every way as represented. 

In conclusion, I beg to thank those who have so generously sup¬ 
ported me in the past, and to express a hope that this work will be 
found useful in our laboratories and factories, and indeed in the 
hands of any person who may refer to it.

NOTICE. 


The “ Albertype ” of a portion of my lower show-room, exhib¬ 
ited in the front of this Catalogue, was prepared by Mr. E. Bier- 
stadt, of this city, expressly for this work. 

The prices placed against the several articles in the following 
Catalogue are for United States legal tender, and are arranged upon 
so low a scale that net cash payments will be required for single 
pieces, except when otherwise agreed. These prices are, of course, 
subject to alterations, according to the values of crude materials 
and labor, and to the fluctuations in the foreign markets. For ex¬ 
ample, I am already advised of a prospective advance on Becker’s 
balances and weights at the beginning of 1873, amounting to about 
10 per cent, on his prices in this catalogue. 

The charges of packing and shipping must, of course, be borne 
by the purchaser; and, in the case of chemicals, unless otherwise 
directed, these will be put into bottles and suitable packages, the ex¬ 
pense of which will be added to the cost of the materials themselves. 

Damages occurring by breakage or otherwise, in transits, are 
never entertained in this business, nor can claims for deductions of 
any kind be allowed, unless notice of the same be given within six days 
of the receipt of the goods. In every case the signed receipt for ar¬ 
ticles in good order will relieve the supplier from all responsibility. 

In ordering goods, it is desirable that full shipping directions 
be given, as otherwise the selection of route will be considered as 
left to my own discretion. The fullest description of goods is also 
solicited, particularly when (as may be done) reference is made to 
any well known foreign catalogue. 

Having engaged the bervices of an experienced glass-blower, 
numerous styles of small apparatus,' not specified in this Catalogue, 
can be well and expeditiously manufactured. When such are re¬ 
quired, it is necessary that the directions contain carefully prepared 
drawings and accurate dimensions. 

All kinds of apparatus can be carefully and accurately repaired 
on the premises by experienced workmen. 

Valuable apparatus, imported specially to order, for moderate 
terms, on commission. When such are imported for scientific insti¬ 
tutions, they are free of duty. 

The large outlay of money incident to the publication of this 
work compels me to make a charge of $1.50 for each copy. This 
will partially cover expenses, and will, I am sure, be cheerfully paid 
by any who desire to consult the work. E. B. B.

CATALOGUE. 


For numbers 1 to 1,248 reference should be made to the Cata¬ 
logue of Dr. H. A. Ward’s Casts of Fossils. This collection con¬ 
tains accurately formed models, and embraces all that has been 
discovered in reference to the Animal Kingdom, in its various sub¬ 
divisions of Vertebrates, Articulates, Mollusks, Radiates, and Pro¬ 
tozoans. Full descriptions will be found in the Catalogue, which, 
as a work of reference, should be in everybody’s library. 

Dr. Ward having paid me the compliment of making this estab¬ 
lishment a special, and indeed, independent of his factory, the only 
depot where his casts can be obtained at the manufacturer’s prices, 
orders are earnestly solicited for these valuable additions to cabinets 
and college col 1 actions. The specimens are well arranged and classi¬ 
fied for inspection, and can be supplied singly or in series. 

Special attention is called to these casts, and a cordial invitation 
is extended to all who may feel a desire to inspect them. The 
extraordinary energy and ability displayed by Dr. Ward, in secur¬ 
ing and collecting, from the most reliable sources, these remarkable 
specimens of past ages, is undoubtedly entitled to the warmest 
encouragement and earnest support on the part of his fellow 
countrymen. His depots, established in London, and on the con¬ 
tinent of Europe, are already giving him important evidence of the 
appreciation in which the people of those countries hold his success¬ 
ful endeavors for the advancement of science, and it is earnestly 
hoped, and indeed confidently believed, that as soon as it shall be 
generally known that a depot has been established here, the people 
of the United States will also extend to the Doctor substantial 
tokens of their approbation. 

Professor Owen, in his popular work on a National Museum of 
Natural History, says: “ A fossil bone, and a colored plaster cast of 
it, are not distinguishable at first sight—scarcely by sight at all. 
The artificial junction of a series of casts of the bones of an unique 



6 E. B. benjamin’s descriptive catalogue 

fossil skeleton, produces a result equivalent, for all the purposes of 
public exhibition, to the articulated skeleton itself. Thus, every 
capital in Europe, the public museum of each civilized community, 
may show to the people the proportion of the creatures of former 
worlds, that science has so restored.”

ELECTRICAL AND GALYANIC APPARATUS. 

Holtz’s ivonderful Induction Electrical Machine as improved 
by Borchard, and first brought into the United States for sale, 
by myself, in 1869. It is the most wonderful discovery, in regard 
to the length of the spark yet known—a spark 6 in. long having 
been obtained from a 12 in. plate machine, and glass perforated 
If in. thick. The remarkable machine, imported by myself, now in 
the possession of Prof. Blake, of Brown’s University, has a 30 in. 
plate, and has produced a spark about 16 in. It was the result of 
the combined intelligence of Messrs. Holtz, Poggendorf, Rienz, and 
Dove; was manufactured expressly for me by Mr. Borchard, and is 
believed to be the best single machine of the kind in the world 
for practical purposes. It must be borne in mind that the ma¬ 
chines I import are all made for me by the inventor , and the secret 
of the long spark has never yet been discovered by the greatest 
savans in Europe, and I presume that it will not be questioned but 
that those made by the inventor himself must inevitably be far 
superior to any imitations or copies; nevertheless, should my cus¬ 
tomers desire them, I am prepared to furnish imitations of this 
celebrated machine as low as any house in America. It should be 
borne in mind that these machines, with the extra appurtenances, 
can illuminate large Geissler tubes, pierce thick glass, show rotation 
by electricity, manufacture Ozone, etc. They are light and portable, 
and easily excited by the use of a sheet of hardened vulcanized 
rubber and a cat skin, and when once excited, are well known to 
retain their electricity from four to five hours. The new and

Brunt, Esq., of this country, consisting of a multiplication of the

this machine at my establishment.

The foregoing arrangement of batteries is the most conve¬ 
nient, cleanly, and available form in use. It is arranged for the 
employment of one solution, which can be kept readily pre¬ 
pared at hand in a tight, ground stoppered bottle. When the 
battery is not in use, the zinc may be raised above the solution 
in the jar (which should be only half-filled with the same); 
and when the operator desires to renew the contact, the zinc is 
simply plunged into the fluid by pressing down the sliding rod. 
The top of the battery being always closed by a tight-fitting 
brass cap, no offensive fumes can escape to influence chemicals 
or the atmosphere in the vicinity. The operator will readily 
perceive that one cell can be employed alone, or any number 
to the extent of six. The seasonable employment of the sliding 
rod obviates any danger of shocks in connecting or disconnect-

This new and unique form of Electrometer is deserving of

quantitatively measured. Prof. Kirchoff has added a valuable 
and interesting photometric attachment, rendering it a very 
easily read, and most complete instrument. It is certainly a 
great step in advance in the quantitative estimation of elec¬ 
tricity, and is receiving great attention from the Physicists of

E. B. BENJAMINS DESCRIPTIVE CATALOGUE 


The foregoing apparatus has come into extensive use both in 
Europe and in this country: filters precipitates, etc., which, with 
the old method, would take, in many familiar instances, four to ten 
hours to filter properly, in a tenth of the time taken by the old 
method. Alluminous, Sillicious, and ordinary sulphide of hydrogen 
precipitations, are quickly filtered from. So convenient and useful 
has it become, and so generally recognized by the profession, that 
it is considered almost an indispensible requisite of every laboratory. 
The illustration shows the arrangement of this pump; full descrip¬ 
tion of the method of employment of this apparatus, and several of 
its excellencies may be found in Johnson’s latest edition of Fres- 
enius’s Quantitative Chemical Analysis, from which I extract the 
following observations, and I have recently introduced an improve¬ 
ment in the working of this apparatus, by which the filtrate may 
be received directly into a beaker, for the suggestion of which I am 
indebted to Dr. Gibbs, of Harvard College. 

“ This apparatus is screwed down on a board fastened to the wall, in such 
a manner that each separate piece of the apparatus is held by a single fasten¬ 
ing ouly, in order to prevent the tubes from being strained or broken by the 
possible warping of the board. On opening the first pinchcock, the water 
flows down the discharge to a depth of thirty feet, carrying with it the air 
which it sucks through the upper tube. The second pinchcock is used to 
regulate the flow of the steam, when the first one is completely open. The 
discharge pipe should have a fall of about thirty feet, and be of a diameter of 
half-an-inch, and end in a sewer or some other arrangement, to convey the water 
away. The filtration is made in the following manner. The receiver standing 
in a metallic vessel is connected by a small glass or rubber tube, with the dis¬ 
charging tube on left of the illustration (having previously been fitted with 
filter). At first, the delivery is gradual, but in a moment or two the filtrate 
runs through in a continuous stream, often so rapidly that one must hasten 
to keep up the supply of liquid. 

“The Platinum Cone is placed in the bottom of the glass funnel, the dry 
paper filter then introduced in the ordinary manner, moistened, and freed 
from all adhering air bubbles by pressure with the finger. A filter so arranged, 
and in perfect contact with the glass when filled with a liquid, will support 
the pressure of an entire atmosphere without the least danger of breaking, 
and the interspace between the folds of the platinum foil is perfectly sufficient 
to allow of the passage of a continuous stream of water.”

sulphide of iron ; the other bulb is partly filled with diluted sulphuric acid; 
the apparatus being placed on the support, revolves on the center, and can 
be fixed by the tliumb-screw in any required position; when the bulb con¬ 
taining the sulphide of iron is raised above the other bulb, the acid is thrown 
back into the right bulb, and its action on the sulphide of iron ceases; other¬ 
wise, when this bulb is placed below, the sulphuric acid flows upon the 
sulphide of iron, and a continuous current of sulphuretted hydrogen gas 
passes off by the bent, glass tube, into the washing flask, and thence 
outward. When the apparatus is not in use, it is simply necessary to elevate 
the bulb containing the sulphide of iron and close the piuchcock on the 
flexible tube.

apparatus, imported only to order.

It consists of a generator and receiver, made of iron boiler-plate, the 
receiver being conical in shape, both connected by means of a strong iron 
tube. In the generator is placed a strong solution of ammonia saturated at 
0°, and this is heated over a large gas flame, the receiver meanwhile being 
immersed in the water. The liquified ammonia passes again into the gaseous 
state, and is re-absorbed by the water in the generator. But in this evapora¬ 
tion, great cold is produced, and the vessel of water is soon frozen. The am¬ 
monia going over can be used indefinitely.

The large cup is filled with porous plaster of Paris, and is connected with 
the bulb-tube opposite to it (which contains a small quantity of mercury), by 
means of a brass tube. The cop of the bulb has a screw cap to hold one of the 
electrodes. The other electrode is screwed to the base, and connects with 
large cup; when the porous cup absorbs the fire-damp gas, the mercury 
presses on the narrow tube, making connection with upper cup, comple¬ 
ting the circuit, and ringing the bell.

The above illustration consists of a vessel in a semi-circular brass frame 
and parallel glass sides, one-fifth of an inch apart. When this vessel is filled 
with a mixture of new milk and water, the appearance of the mixture is ex¬ 
amined by placing a candle at a distance of three feet from one side of it, and 
the eye close to the other side ; the presence of a certain proportion of cream 
renders the figure of the candle flame indistinct. The smaller the quantity 
of milk required to obviate the candle light the better is the quality of 
the milk. With the above comes a glass graduated vol cylinder on foot, with 
spout, and a graduated vol pipette. The manner of operating with this, show¬ 
ing the precise quantity of butter indicated in the milk, will be furnished 
with the instrument.

2641. —Magneto-Electric Apparatus, new invention, for firing 

the fuses, etc., in mine blasting. $100.00 

In this apparatus the armature A A is always in contact with the j>oles 
of the magnet _ZV, 0, JS. It is supported by a piece of metal, B M, which 
turns around a horizontal axis, a ; this piece presents a kind of handle, B a, 
haying a knob at B, upon which one strikes with the finger in order to 
produce the withdrawing of the armature; thus, at the moment of this 
withdrawal, a first induction current is produced, passing contemporaneously 
with the movement which causes it, through the wire surrounding the 
extremities of the magnet. As long as one keeps the armature withdrawn 
from the magnet, the apparatus is inert; but as soon as one ceases to bear 
down on the button B , the armature, impelled by a spring which acts on the 
lever a B, drawn besides by the magnet, it turns instantly to the contact of 
the poles NS] a second current is produced in a contrary direction to the first, 
of equal intensity, as can be easily demonstrated with the galvanometer. 
There is also connected with the instrument a stop X, the employment of 
which holds the armature in a fixed position, so that it is impossible for elec¬ 
tricity to pass. This instrument works in all weathers; and, while it is im¬ 
possible to fire the fuse when the stop X is placed upon the armature, a 
simple withdrawal of the stop X, and a smart rap of the finger upon the 
handle B , will instantly fire a fuse by the electric current through a wire 500 
to 600 yards in length.

(The assay ton weights have been introduced by Dr. C. F. Chandler, of the 
School of Mines, Columbia College, New York, where they are in use for con¬ 
venience in the assay of ores. The weight denominated by Dr. Chandler 
“One A. T.,” equals 29,1666 grammes, and contains, consequently, as many 
milligrammes as there are troy ounces in a ton avoirdupois of 2,000 lbs. 
Therefore, if One A. T. of ore assays 1 milligramme, the ton contains, of 
course, 1 ounce troy.)

CHEMICALS AND REAGENTS. 


This List comprises the majority of Chemicals I keep, though 
there are a number of strictly commercial articles that usually rank 
under the head of Chemicals, which are omitted, but which I have 
the fullest facilities for shipping at the lowest market rates. 

The prices given are for usual quantities. If large amounts of 
any article herein priced are desired, I should be pleased to give the 
benefit of the lowest market quotations, according to the market 
values at the time. 

I have frequently procured Crude Stock Chemicals, Drugs, and 
other articles for class illustrations in Organic and Applied Chem¬ 
istry, for my patrons at a distance, and will take pleasure in serving 
them in this manner in the future, charging only a small per centage 
for my time and trouble. 

• rr , 

Standard Test Solutions, according to Fresenius and other au¬ 
thorities, carefully prepared to order at moderate rates. 

Great attention is paid to neatness, cleanliness and accuracy in 
dispensing reagents. 

Complete collections of the elements made and arranged on de¬ 
mand ; also suits of the principal spectroscopic salts, neatly put up 
in glass stoppered vials, for either class illustrations or Laboratory 
purposes.

MINERALOGICAL 


AND 

GEOLOGICAL DEPARTMENTS. 


During the past year, I have organized and incorporated into 
this establishment a Mineralogical and Geological department. My 
aim and desire is to furnish to those requiring them, characteristic, 
and, at the same time, Good Cabinet Specimens, for lecture and other 
purposes, at moderate prices ; also, the usual sets and series for Stu¬ 
dents’ use, Blow-pipe purposes, etc. Each specimen, without regard 
to size or price, will be distinctly labeled with full name and local¬ 
ity. Dana will be followed in all instances. 


MINERALS. 

3473. —A Complete Set of Minerals, with pasteboard trays 

for placing them in, each specimen being perfectly characteristic and 
illustrating all the ordinary crystalized forms in which they occur. 
In all, 200 specimens; size about 2£ x 2-j- inches. This series will be 
found to be very suitable for academies, seminaries, the smaller col¬ 
leges, etc. $50.00 

3474. —A Collection similar to the above, but more complete, 
containing 300 specimens, 2-| x 2-J inches, neatly and securely packed 
in wooden boxes; each mineral being numbered, with catalogue oi 
same. This collection is put up and selected by a practical and 
experienced mineralogist, and will be found quite complete. 

Packed, $75.00

208 E. B. BENJAMIN S DESCRIPTIVE CATALOGUE 

3480. — A Collection of minerals of most excellent size, and of a 
character suitable for placing on the shelves of the College Cabinet, 
at the uniform price of 50 cents per specimen, averaging about 3x3 
inches in size. These minerals were collected by a well known 
mineralogist of this city, and each specimen is a perfect example of 
its kind. They are not completely classified, and, therefore, I will 
sell them singly at an extremely low figure. Some of these, for 
example, Kyanite, Tourmaline, Zinc Ores, etc., are really deserving of 
very much higher prices. The greater part of this collection is 
from American localities.

and group is characterized by its distinctive fossil or fossils. This 
collection of rocks has received the great approval of all the col¬ 
leges who have purchased it, and is certainly deserving of notice, 
not only on account of its having been obtained entirely from New 
York State, but, also, for its completeness. It is believed to be the 
only collection of the kind ever put on sale in this country, and 
will be found to be eminently well adapted for teaching Dana’s

will be found to be unique examples of their class, .and every class 
most fully illustrated. They have been gathered together from the 
most celebrated localities of the world, and contain specimens val¬ 
ued at $250 to $300 each.

3533.—Apparatus* for illustrating Hinrich’s Elements of 
Physics. 


For exclusive use in the Lectures (see School Laboratory, 1871, p. 60), the 
teacher should procure as much as possible of the larger apparatus and finer 
specimens of crystals, minerals, etc., mentioned in the work. No general direc¬ 
tions can here be given; the wants and means of the school will have to be 
consulted in making out the order. The teacher ought, however, always to 
give the precedence to the apparatus to bo used by the students in the Labor¬ 
atory Practice, if the means of the school do not permit the purchase of this 
necessary apparatus and the more costly apparatus also This simple appar¬ 
atus required for the demonstration of tho Fundamental Laws of Electricity 
(see 341 to 372), is more important to the student, and therefore to the school, 
than the more expensive and more powerful machines (373 to 380); that is, the 
simple apparatus for students’ experiments must be obtained first; the fine 
electrical machines and batteries should thereafter be procured as soon as pos¬ 
sible. The necessary apparatus for Student’s Laboratory Practice is divided 
into two distinct groups, viz.: I. Apparatus placed at convenient points in 
the Laboratory, to be used by students in general; II. Sets of Apparatus, put 
up in a separate tray, of wood or pasteboard, sufficient to demonstrate any 
given article iu the book. (See article 492 in the Elements of Physics ) 

Every piece of apparatus should be labeled. (See El. Phys , 495-’96.) Be¬ 
low, the principal fixed apparatus for general use is enumerated. A few sets 
for the demonstration of separate articles have been added, simply to serve as 
examples. A full enumeration of all the sets required would, demand too 
much space. 

I.—APPARATUS FOR GENERAL USE. 


7. Meter Rods, of wood or brass, sev¬ 
eral, labeled No. 1, No. 2, etc.
